Description

Technical Field

[0001] The utility model relates to the technical field related to sewage treatment, and in particular to a sewage treatment separation device. Background Art

[0002] The pollutants contained in domestic sewage are mainly organic matter and a large number of pathogenic microorganisms, which are easy to decompose and produce foul odors. Bacteria and pathogens use organic matter in domestic sewage as nutrition and multiply in large numbers. Therefore, domestic sewage must be treated before being discharged. Before thoroughly disinfecting the sewage bacteria, a solid-liquid separation device is required to separate the solid matter in the sewage to avoid damage to the subsequent filtration equipment caused by the solid matter. In the process of sewage treatment and separation, flocculants and other powders are usually added to the sewage, and aeration treatment is performed on it at the same time, so that the solid impurities after the sewage reaction are precipitated to the bottom of the water. However, the existing aeration method is relatively simple. During the aeration process, the sewage cannot fully contact with the air and powder, which leads to low overall treatment efficiency.

[0003] To this end, we propose a sewage treatment separation device to solve the above problems. Utility Model Content

[0013] When the utility model is in use, through the cooperation of the transmission gear and the transmission belt, a group of stirring rods can be driven to rotate, so as to stir and mix the sewage, so that it can fully contact with the medicine powder. At the same time, during the rotation of the stirring rod, external air can enter the sewage pool through the ventilation groove, the air guide pipe and the air hole, so as to contact the sewage from the inside, expand the contact area between the sewage and the air, and thus achieve a better aeration effect, so that the sewage can react with the medicine quickly, and the polluted impurities generated after the reaction are precipitated at the bottom of the water; the operation of the hydraulic rod can drive the filter frame to move, and then the sewage after the reaction is completed is filtered through the action of the filter screen, so that the solid-liquid separation is convenient for subsequent treatment.

A filter frame 2 is arranged in the inner cavity of the shell 1. The side walls at both ends of the shell 1 are respectively connected with longitudinal hydraulic rods 201. The upper end of the hydraulic rod 201 is connected to the side wall of the filter frame 2. The operation of the hydraulic rod 201 can drive the filter frame 2 to move, and then filter the sewage after the reaction is completed through the action of the filter screen 3. A filter screen 3 is installed on the lower end surface of the filter frame 2. The filter screen 3 filters the treated sewage, so that the solid-liquid separation is convenient for subsequent treatment. At the same time, the filter frame 2 is a hollow design, which can quickly discharge the separated liquid.

[0024] A horizontal support plate 4 is connected to the inner wall of the filter frame 2, and a longitudinal through hole 401 is opened on the side wall of the support plate 4. The inner wall surface of the through hole 401 is covered with a smooth layer to ensure that the stirring rod 5 can rotate smoothly. The upper end of the stirring rod 5 extends to the upper side through the through hole 401, and a limiting plate 402 is connected to the side wall of the upper end of the stirring rod 5 to limit the position of the stirring rod 5 and prevent it from leaving the range of action.
